为探讨低浓度甲醛接触对工人健康的影响 ,对 79名甲醛作业工人进行了健康检查及肺功能测定。结果表明甲醛对作业工人的主要危害表现为上呼吸道症状体征发生率增加 ,接触组肺功能异常率增高 ,且以小气道功能异常为主。提示长期接触低浓度甲醛损害工人呼吸系统健康 ,对肺功能损害属于阻塞性肺通气功能障碍 ,肺功能测定不失为甲醛作业工人健康监护的理想指标。 In order to investigate the impact of low concentration formaldehyde exposure on workers’ health, 79 formaldehyde workers were inspected for their health and lung function. The results showed that the main hazards of formaldehyde to workers were as follows: the incidence of signs and symptoms of upper respiratory tract increased; the rate of abnormal lung function in the contact group increased; and the abnormality of small airways was the main factor. Prompted long-term exposure to low concentrations of formaldehyde damage to respiratory health of workers, pulmonary function impairment is obstructive pulmonary ventilation dysfunction, lung function tests are ideal indicators of health workers in formaldehyde care workers.
